Description

Technical Field

[0001] This invention relates to the field of wastewater discharge and recycling technology, specifically a wastewater discharge and recycling device for steam turbines in thermal power plants. Background Technology

[0002] As a crucial link in power supply, the core equipment of a thermal power plant—the steam turbine—plays a vital role in the conversion of steam energy into electrical energy. However, while operating efficiently, the steam turbine also generates a certain amount of wastewater containing high levels of salt, alkalinity, and other impurities. If this wastewater is discharged directly without proper treatment, it will not only pollute the environment but may also damage the steam turbine itself and downstream equipment, causing serious problems such as steam-water embrittlement and caustic embrittlement of metals.

[0003] Traditional methods for treating steam turbine wastewater have many limitations. On the one hand, filtration and sewage discharge operations often rely on manual intervention, which is inefficient and makes it difficult to ensure the continuity and stability of the treatment process. On the other hand, the impurities and waste generated during the treatment process lack effective collection and treatment methods, which can easily cause secondary pollution to the environment.

[0004] Based on this, a wastewater recycling device for steam turbines in thermal power plants is now provided, which can eliminate the drawbacks of existing devices. Summary of the Invention

This process not only improves the efficiency of wastewater treatment but also effectively ensures the stability of the effluent quality. Finally, once the wastewater has undergone neutralization treatment and reached the preset water quality standard, the outlet valve automatically opens, allowing the treated wastewater to be smoothly discharged from the system for subsequent use or discharge.

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] In one embodiment, such as Figures 1-6 As shown, a wastewater collection device for steam turbines in a thermal power plant includes a treatment cylinder 1. An inlet pipe 11 is fixed to the top of the left side wall of the treatment cylinder 1. A filter bucket 2 is fixedly installed inside the treatment cylinder 1. A filtration area 21 is provided at the bottom of the inner side wall of the filter bucket 2, and several filter holes 211 are provided in the filtration area 21. A buffer inclined plate 14 slides inside the treatment cylinder 1, and the buffer inclined plate 14 is located above the filter bucket 2. The upper end of the buffer inclined plate 14 is fixedly connected to the top of the inlet pipe 11 through a damping buffer member 13. The buffer inclined plate 14 is located below the inlet of the inlet pipe 11. A collection structure 23 is provided at the upper end of the filter bucket 2. The lower part of the treatment cylinder 1... A main cylinder 5 is fixed at one end, and dosing pipes 54 are symmetrically fixed on the main cylinder 5. A stirring cylinder 51 is set inside the main cylinder 5, and a stirring structure 4 is set inside the stirring cylinder 51. A drive structure 3 for providing power to the collection structure 23 and the stirring structure 4 is set at the upper end of the treatment cylinder 1. A separation frame 6 is fixed at the lower end of the main cylinder 5. A water outlet pipe 52 is fixed at the lower end of the stirring cylinder 51. The stirring cylinder 51 and the separation frame 6 are connected through the water outlet pipe 52. A separation structure 65 is set inside the separation frame 6. A drainage hopper 61 is fixed at the lower end of the separation frame 6. A drainage pipe 62 is fixed at the lower end of the drainage hopper 61. A slag discharge inclined plate 63 is fixed at the left end of the separation frame 6.

[0028] In this embodiment, wastewater is introduced into the treatment cylinder 1 through the inlet pipe 11. The wastewater first comes into contact with the buffer inclined plate 14, which slows down the water flow and prevents the water from directly impacting the filter hopper 2. The wastewater then enters the filter hopper 2, passes through the filter holes 211 of the filtration area 21, and larger impurities are filtered out and remain in the filter hopper 2. The filtered wastewater continues to flow downwards.

[0029] Wastewater enters the mixing drum 51, and simultaneously, a suitable neutralizing agent is added through the dosing pipe 54. At this point, the drive structure 3 starts working, providing power to the mixing structure 4. The mixing structure 4 begins to agitate the wastewater, ensuring that the wastewater and neutralizing agent are uniformly mixed within the mixing drum 51.

[0030] The stirring process accelerates the mixing and reaction of wastewater and neutralizing agent to achieve the best neutralization effect. The stirred wastewater enters the separation frame 6 through the outlet pipe 52. Inside the separation frame 6, the separation structure 65 further separates the wastewater, removing fine impurities.

[0031] The separated impurities flow out of the device along the slag discharge ramp 63. The treated clean water flows into the drain hopper 61. The clean water is then discharged through the drain pipe 62 and can be used in other production processes of the thermal power plant or for other reuse.

[0032] In an optional embodiment, the collection structure 23 includes a rotating cylinder 231 rotatably mounted on the upper end of the filter bucket 2. The upper end of the rotating cylinder 231 penetrates the upper end of the processing cylinder 1. The rotating cylinder 231 is rotatably connected to the processing cylinder 1. A slag inlet is provided at the bottom of the side wall of the rotating cylinder 231. A fixing rod 235 is installed inside the rotating cylinder 231 and is fixed to the filter bucket 2. A transport blade 236 is fixed on the outer wall of the fixing rod 235. A plurality of drainage holes 2361 are provided on the transport blade 236. A scraper 234 is fixed at the bottom of the outer wall of the rotating cylinder 231. The scraper 234 is in contact with the filtration area 21 and corresponds to the position of the slag inlet. A slag outlet 232 is provided at the top of the outer wall of the rotating cylinder 231. A toothed ring 233 is fixed on the outer wall of the rotating cylinder 231. The toothed ring 233 is located at the upper end of the processing cylinder 1 and is connected to the drive structure 3.

[0033] It should be noted that when the drive structure 3 is started, it drives the rotating cylinder 231 to rotate through the toothed ring 233. At the same time, the scraper 234 scrapes along the surface of the filter area 21 to ensure that impurities are effectively removed from the filter hopper 2. The impurities enter the interior of the rotating cylinder 231 through the slag inlet.

[0034] Since the fixed rod 235 and the transport blade 236 are fixed to the filter bucket 2, and the rotating cylinder 231 rotates relative to the filter bucket 2, when the rotating cylinder 231 rotates, the transport blade 236 remains fixed and rotates relative to the rotating cylinder 231, thereby transporting the impurities attached to the filter area 21 upward to the slag discharge port 232.

[0035] An opening is made in transport blade 236 to allow wastewater to pass through, but to prevent larger impurities from passing through. In this way, the wastewater can continue to flow downwards, while the impurities are captured and transported by transport blade 236.

[0036] In an optional embodiment, a plurality of support columns 12 are fixed to the upper end of the processing cylinder 1. The upper end of the support column 12 is fixedly connected to the slag collection component 24. The slag collection component 24 is provided with a slag collection groove 241. A slag discharge inclined block 242 is fixed to the middle of the upper end of the slag collection component 24. The slag discharge inclined block 242 is rotatably connected to the rotating cylinder 231, and the slag discharge inclined block 242 is located below the slag discharge port 232.

[0037] It should be noted that after the impurities are discharged from the slag discharge port 232, they fall onto the slag discharge ramp 242. The impurities slide down the ramp surface of the slag discharge ramp 242 into the slag collection tank 241. The impurities in the slag collection tank 241 can be periodically discharged or further treated.

[0038] In an optional embodiment, the drive structure 3 includes a motor 301 mounted on the right side of the processing cylinder 1. The output end of the motor 301 is fixedly connected to a main wheel 302. The main wheel 302 is driven by a driven wheel 304 via a transmission belt 303. The lower end of the driven wheel 304 is fixedly connected to a main gear 305. The main gear 305 is rotatably mounted on the upper end of the processing cylinder 1 and meshes with a gear ring 233. The gear ring 233 is connected to the stirring structure 4.

[0039] It should be noted that when motor 301 is running, it drives main wheel 302 to rotate. Main wheel 302 transmits power to driven wheel 304 through transmission belt 303. Driven wheel 304 and its lower fixed main gear 305 rotate accordingly. The rotation of main gear 305 drives the gear ring 233 that meshes with it to rotate.

[0040] The rotation of the toothed ring 233 indirectly drives the stirring structure 4 to perform stirring operations and the collection structure 23 to collect impurities.

[0041] In an optional embodiment, the stirring structure 4 includes a main gear 305 and three driven gears 401 rotatably mounted on the upper end of the processing cylinder 1. The main gear 305 and the three driven gears 401 are all meshed with the gear ring 233. A connecting rod 402 is fixed to the lower end of the main gear 305 and the three driven gears 401. The connecting rod 402 extends through the processing cylinder 1 and the filter bucket 2 into the interior of the stirring cylinder 51. Several stirring rods 403 are fixed to the outer wall of the connecting rod 402 inside the stirring cylinder 51. The filter bucket 2 is provided with a through hole 22 that is adapted to the connecting rod 402.

[0042] It should be noted that the main gear 305 drives the three driven gears 401 to rotate through the gear ring 233. The rotation of the main gear 305 and the driven gears 401 is transmitted to the stirring rod 403 through the connecting rod 402. The stirring rod 403 rotates in the stirring drum 51 to stir the wastewater and accelerate the mixing and reaction of the wastewater with the neutralizing agent in the stirring drum 51, thereby accelerating the pH value of the wastewater to reach the discharge standard.

[0043] In an optional embodiment, the separation structure 65 includes a second motor 651 mounted on the separation frame 6. A second main wheel 652 is fixed to the output end of the second motor 651. The second main wheel 652 is connected to the cleaning structure 66 via a second transmission belt 657. An active roller 653 is fixed to the end of the second main wheel 652 away from the second motor 651. The active roller 653 is rotatably mounted inside the separation frame 6. A driven roller 656 is rotatably mounted inside the separation frame 6 on the side near the slag discharge inclined plate 63. A separation belt 654 is sleeved on the outer wall of the active roller 653 and the driven roller 656. A plurality of separation ports 655 are opened on the separation belt 654.

[0044] It should be noted that when motor 651 operates, it drives main wheel 652 to rotate. Main wheel 652 simultaneously drives cleaning structure 66 via transmission belt 657, and the rotation of main wheel 652 further drives drive roller 653 to rotate. Driven roller 653 and driven roller 656 together support and drive separation belt 654 to rotate. The mixture of wastewater and waste residue falls onto the rotating separation belt 654. Through the several separation ports 655 opened on the separation belt 654, the waste residue is intercepted, and the wastewater flows away through the separation structure.

[0045] The retained waste residue is discharged through the slag discharge inclined plate 63.

[0046] In an optional embodiment, the cleaning structure 66 includes a driven wheel 661 rotatably mounted on the separation frame 6. The driven wheel 661 is connected to the main wheel 652 via a transmission belt 657. One end of the cleaning structure 66 is fixedly connected to a cleaning roller 662, which is rotatably mounted at the connection between the separation frame 6 and the slag discharge inclined plate 63. The cleaning roller 662 is in contact with the outer surface of the separation belt 654.

[0047] It should be noted that when motor 2 651 is running, it drives main wheel 2 652 to rotate. Main wheel 2 652 transmits power to driven wheel 2 661 through transmission belt 2 657. Driven wheel 2 661 drives cleaning roller 662 to rotate. The rotating cleaning roller 662 is in close contact with the outer surface of separation belt 654 to scrape off the residue. The cleaned residue may be discharged through slag discharge inclined plate 63.

[0048] In an optional embodiment, a scraper block 64 is fixed on the slag discharge inclined plate 63, and the scraper block 64 is in contact with the outer surface of the cleaning roller 662.

[0049] It should be noted that when the cleaning roller 662 passes the scraper block 64, the scraper block 64 will further scrape off the residue on the cleaning roller 662.

[0050] The cleaned residue slides down the slag discharge ramp 63 under the action of gravity and is eventually discharged from the system.

[0051] In an optional embodiment, a plurality of pH water quality monitors 55 are installed inside the stirring tank 51, and a water outlet valve 53 is installed on the water outlet pipe 52. The pH water quality monitors 55 and the water outlet valve 53 are connected to an external controller.

[0052] It should be noted that during the wastewater treatment process, the pH water quality monitor 55 continuously monitors the pH value of the water inside the mixing tank 51 and transmits the data to the external controller in real time. The external controller compares the received pH value data with the preset discharge standards. If the water pH value meets the discharge standards, the external controller sends a signal to the outlet valve 53, causing it to open and allowing wastewater to be discharged. If the water pH value does not meet the discharge standards, the external controller keeps the outlet valve 53 closed.

[0053] The above embodiment discloses a wastewater recycling device for steam turbines in thermal power plants. Wastewater is introduced into the treatment cylinder 1 through the inlet pipe 11. The wastewater first comes into contact with the buffer inclined plate 14. The buffer inclined plate 14 is fixedly connected to the top of the inlet pipe 11 through the damping buffer 13, which effectively slows down the water flow speed, prevents the water flow from directly impacting the filter bucket 2, protects the filter bucket 2 and extends its service life. The wastewater then flows into the filter bucket 2 and passes through the filter holes 211 of the filtration area 21. Larger impurities are filtered out and remain in the filter bucket 2.

[0054] When the drive structure 3 (motor 301) is started, it drives the main gear 305 to rotate through the main wheel 302, the transmission belt 303 and the driven wheel 304. The main gear 305 meshes with the gear ring 233. The rotation of the gear ring 233 drives the rotating drum 231 to rotate. The scraper 234 at the bottom of the rotating drum 231 scrapes along the surface of the filter area 21, removing impurities from the filter hopper 2 and entering the interior of the rotating drum 231 through the slag inlet. At the same time, since the fixed rod 235 and the transport blade 236 are fixed to the filter hopper 2, when the rotating drum 231 rotates, the transport blade 236 rotates relative to the rotating drum 231, transporting the impurities upward to the slag discharge port 232. After the impurities are discharged from the slag discharge port 232, they fall on the slag discharge inclined block 242 of the slag collection component 24 and slide down the inclined surface into the slag collection trough 241 for periodic discharge or further treatment.

[0055] After filtration, the wastewater continues to flow downwards into the mixing drum 51. A suitable neutralizing agent is added through the dosing pipe 54. The rotation of the main gear 305 not only drives the collection structure 23 to work, but also drives the three driven gears 401 to rotate through the gear ring 233. The connecting rod 402 at the lower end of the main gear 305 and the driven gears 401 drives the stirring rod 403 to rotate inside the mixing drum 51, stirring the wastewater and ensuring that the wastewater and neutralizing agent are mixed evenly, thus accelerating the neutralization reaction.

[0056] At the same time, a suitable neutralizing agent is added through dosing tube 54.

[0057] During wastewater treatment, the pH water quality monitor 55 continuously monitors the pH value of the water inside the mixing drum 51 and transmits the data to the external controller in real time. The external controller compares the received pH data with preset discharge standards. If the pH value meets the discharge standards, the external controller sends a signal to the outlet valve 53, opening it and allowing wastewater to be discharged through the drain pipe 62. If the pH value does not meet the discharge standards, the external controller keeps the outlet valve 53 closed and may trigger an alarm or send a prompt message to the operator to take further wastewater treatment measures.

[0058] The stirred wastewater enters the separation frame 6 through the outlet pipe 52. Motor 651 drives the main wheel 652 to rotate, and the main wheel 652 simultaneously drives the cleaning structure 66 and the drive roller 653 to rotate via the transmission belt 657. The drive roller 653 and the driven roller 656 together support and drive the separation belt 654. The wastewater and waste residue mixture falls onto the operating separation belt 654. Through the separation port 655 on the separation belt 654, the waste residue is trapped, and the wastewater flows through the separation port 655 into the drain hopper 61 below, and is finally discharged through the drain pipe 62. The cleaning roller 662 of the cleaning structure 66 closely adheres to the outer surface of the separation belt 654, scraping away residue. When the cleaning roller 662 passes the scraper block 64, the scraper block 64 further scrapes away the residue on the cleaning roller 662. The cleaned residue is discharged through the slag discharge inclined plate 63.

[0059] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
